T0 (6 whom it may concern:

Be it known that I, THOMAS W. LIPIIN- oor'r, of Rockford, county of \Vinnebago, and State of Illinois, have invented certain Improvements in Oil-Cans, of which the following is a specification.

My said invention relates to certain devices or attachments for oil-cans and like reservoirs for oil and other liquids, so constructed and arranged with reference to such vessels that by their use the contents of such vessels may be removed therefrom into lamp-bowls and other receptacles with quickness and convenience and cleanliness without waste of the liquids. V My said improvement will be hereinafter fully described with reference to the accompanying drawings, in which Figure l represents a central vertical section of an oil-can and of tubes 0 and F and elevations of two pipes, D and G, partly in section, and alsoa section of a portion of a lamp; and Fig. 2, a detail view of some of the parts.

In the drawings, A indicates the oil-can; l3,the cap for the same, fitting downupon the neck of the can and fastened thereto either by corresponding screw-threads upon the two parts,or else by close frictional contact in case these two parts are made with plain smooth surfaces with that view. The cap isprovided with a long tube, 0, and a short tube, F, both passing through it and fastened therein by soldering or otherwise, so as to make airtight joints with it,and both projecting alittle above it,while the long tube 0 extends nearly to the bottom of the can, but the short one only alittle way below the neck of the same. The tubes should stand at a slight inclination to each other and be just so far apart as to afford sufficient space between them for the pipes D and G to be compressed and forced between them, as hereinafter specified. The tubes may bemade of any metal or other suitable material, and had better be made of some material that will resist the corrosive action of the liquids to be transferred.

piece, H, in order that air may be forced into the pipe from the mouth.

D is another like flexible pipe, made of like material, having its upper end fastened in like manner upon the top end of tube O,while the other end may lead into lamp bowl E, or wherever else required.

The theory of the operation of my device is, that when the can is filled or partially filled with any liquid-oil, for instanceand air is forced in upon the liquid by blowing from the month or otherwise through pipe G, the liquid will be forced by the air up through the tube 0 into the pipe D, and thence into bowl E, and when it has once begun to flow down to a point below the surface of theliquidwithin the can it will then continue to flow without further application of force, and if during such flowing the lamp-bowl be raised to a higher level than that of the surface of the liquid in the can the current will be reversed, and the contents of the lamp-bowl be returned into the can again. The tube 0 having no valve, so soon as the liquid is started to flow either out of the can into the lamp or out of the lamp into the can the pipe G remains open, though it be in a pendent position, and allows free passage of air both ways. If, however, both pipes D and G were left open when the device is not in use for the transfer of liquids, the liquidjn the can would waste or give offense by evaporation. Such a result is prevented effectually and simply by bending the bodies of each of the flexible pipes D and G ,and forcing them between the two tubes 0 and F, thus compressing and closing them, so as to prevent the escape or the passage either way of vapor from the liquid, as shown in Fig. 2.

It is plain that the perfect operation of my device is secured without the use of valves, stop-cocks, or other complicated parts, and that when not in operation no such parts are needed, evaporation being effectually stopped.

It is obvious that my device or apparatus consisting of the cap B and the two tubes 0 and F and their pipes may be applied to and used in connection with any containing-vessel for liquids having a neck corresponding with cap B.

t 1 WVhat I claim as my invention, and desire to pipes when compressed and forced into such 10 secure by Letters Patent, is- I space for the purpose of preventing the escape The combination of the described cap B and of vapor when required substantially as dethe tubes 0 and F, provided, respectively, scribed. 5 with flexible pipes D and G the pipes bein V 3 T fastened in the cap in. such ju xtaposition in THOMAS LIPl D GOTT' lation to each other as to afford just sufficient XVitncsses: space between their upper ends for receiving J.
